Tokyo, Japan Filed Mar. 28, 1968, Ser. No. 716,778 Int. Cl. 133% 15/30 US. Cl. 100-100 21 Claims ABSTRACT OF THE DISCLOSURE A transportable press for scrap cars comprises a bed and a plate located above said bed and movable towards and away from the bed to crush scrap cars placed on the bed and motor means to move the plate. Preferably, the bed carries feeding means to feed scrap cars onto the plate.

The present invention relates to a press for crushing scrap cars compactly so as to reduce the volume and make them easily transportable.

With coming into wide use of cars these days, the quantities of scrap cars are yearly increasing tremendously. Generally, these scrap cars are dumped in designated car graveyards, and are thence transported to melting plants for scrap cars to be regenerated as iron material. For the reason that an ordinary truck can be loaded with only one or two scrap cars for transportation, the cost of transportation is extremely high.

The object of this invention is to provide a new press for scrap cars for crushing scrap cars compactly so as to make tnansportable efficiently by enabling a common truck to take five or six cars on board thereof.

Another object of this invention is to provide a press equipped with means for bringing used cars accurately and infallibly in the pressing position.

Another object of this invention is to provide the press with means for discharging crushed scrap cars smoothly from the press.

Still another object of the invention is to provide a press which can be mounted on an automobile or a motor truck.

According to the feature of this invention, the present scrap car press comprises a bed for receiving a scrap car; a plurality of hydraulic cylinders mounted around the circumference of said bed; an elevating plate located over said bed and connected with the rams of the hydraulic cylinders reciprocating; compression means, carried by said elevating plate for moving the elevating plate towards and away from the back; means for bringing used-cars onto said bed; and means for discharging compressed scrap cars from the bed.

When a press manufactured according to the present invention is utilized in practice, a scrap car placed on the bed, especially its roof portion, will be crushed to become a flat and compact lump by the pressing action of the elevating plate. Further, said scrap cars thus made flat can be piled up one upon another, so that five or six' cars can be loaded on board an ordinary truck, and thus the cost and labor required for transportation can be greatly saved.

Other objects and advantages of the present invention will become apparent from the further following description taken in connection with preferred embodiments of the invention as shown in the appended drawings, in which:

FIG. 10 is a side view of the fifth embodiment.

Referring to the drawings, the first embodiment of a press compressor for scrap cars taken in FIGS. 1 to 3 will be described. The oblong bed 1 laid on the floor F is provided on the four corners of said bed with hydraulic cylinders 2 set respectively vertically and upright as pillars'; and the upper end of the ram- 3 of each of said cylinders is secured to an oblong elevating or press plate 4. Each of said cylinders 2 is connected with each other with a bar 5 in the manner in which one side is open, so that there is formed on said bed 1 a space C having on its one side a delivery gate 6 surrounded with cylinders each, bar and elevating plate.

A hydraulic press jack 7 is vertically mounted centrally on the upper surface of said elevating plate 4, and the ram 8 of the jack 7 projecting underneath said elevating plate 4, said projecting end being secured to an oblong pressing plate or foot 9. Said pressing or foot plate 9 is lowered down near to the bed 1 and again elevated up back to the original position by operation of the jack 7.

For delivering or feeding scrap cars into said space C, a device operated by a jack or jacks is adopted. Two fluid operated jacks 10 are horizontally mounted respectively, one on each side of the front of the lower face of said elevating or support plate 4 with a plurality of brackets 11, each ram 12 of both cylinders being mounted at its end with a trolley 18. Said trolley 18 is U-shaped having a pair of rollers, 17; said trolley 18 is provided at its lower end with a fitting ring 16 having a hook 16a; and said ring 16 is clamped to the end of said ram 12 with set bolts I19. The fluid operated jack or jacks together with the trolley constitute the feeding device for the press. The rope means 13 hooked onto said hook 16a comprises a wire rope 1-4 and two wire ropes 14a attached with hooks 15 which are connected with the lower end of said rope 14. For the purpose of moving said trolley, two rails 21 whose section is I-shaped are located underneath said elevating plate 4 to form two beams 20 projecting from the back end of said elevating plate; and the rollers 17 of said trolley are mounted on the flanges of the lower ends of said I-shaped rails. When the ram 12 is extended from its jack 10, the trolley will run on the rails 21 and will move the rope means 13 out of the space C; when the ram 12 is telescoped, the rope means 13 will be moved to the center of the space C.

There is provided movable chute means in order to discharge scrap cars processed by compression from the space C. The chute board 22 is an oblong board slightly smaller than said bed 1, the rear end of said board being connected swingably with hinges 23 provided on both sides of the back of said bed with pins 23a. As driving means for tilting said chute board22 with said pins 23a as the center of movement, the one end of the wire rope 24 is tied with the fore end of said chute board; said rope is put over pulleys 25, 26 mounted onto the coupling bars 5 on the front and is drawn forward to be connected thence with the rain 28 of the hydraulic cylinder 27 vertically mounted onto the fore end of said bed 1. When the ram 28 projects upon driving of the said cylinder 27, said chute board 22 is staying horizontally on the bed 1, but when the ram 28 has receded, said chute board 22 will thereupon become inclined with the pins 23a as the center of movement upon being drawn by said wire rope 24.

In the operation of the present device, the rope means 13 which is in the condition as shown in FIG. 1 is transferred out of the machine by extending the telescopic jacks 10, and each of the hooks 15 is hooked on the scrap car G. Next, by extending the jacks 2 the elevating plate 4 is lifted upward carrying the scrap car with it. By telescoping the jacks said rope means 13 is transferred into the pressing space C, thereby bringing said car G into said space C. Thereupon, the elevating plate 4 is lowered by telescoping the jacks 2, thereby putting said scrap car G down on the bed 1. The hooks 15 are thence put off the scrap car. By operating the press jack 7 the pressing plate 9 is lowered, thereby crushing said scrap car G through. Said compression should be applied preferably to the roof part of the scrap car. When said compression is over, the pressing plate 9 is elevated; said rope means 13 is thereafter shifted again out of said space C, and another scrap car may be brought into said space C through the similar operation as aforementioned; and thus another scrap car is put down on top of the already compressed scrap car to be similarly compressed. In this manner, the feeding and compression of scrap cars are repeated so that the compressed scrap cars may be piled up. When five or six scrap cars have been piled up, the chute board 22 is tilted by operating of the jack 27, thereby discharging the scrap cars piled on said chute board down outwardly. When and if a loading platform of a dump truck is arranged and placed at the delivery gate 6, the scrap cars will be transferred onto said dump truck. The scrap cars will be finally transported to melting regeneration plants.

Now, another embodiment of the inventive device will be described in the following in reference to FIG. 4. The box-shaped pressing member 39 is provided and secured to the underside of the elevating plate 34. This embodiments disburses with the hydraulic cylinder 7, ram 8 and pressing plate 9 of said previous embodiment of the invention. Said pressing member 34 has a height such as to protrude into said pressing space C when the elevating plates goes down. The other parts of the construction are substantially identical with that of FIG. 1. Furthermore, the structural elements of the present example of embodiments 31 to 36 and 40 to 58 are likewise substantially identical with the corresponding counter parts 1 to 6 and 10 to 28 of the previous device. Scrap cars may be piled up in a plural number of stacks as high as to be subjected to the compression force of said pressing member 39 in the space C through the manner similar to the said means for bringing in,

and thereafter the cars may be crushed with said pressing member 39 upon the descent of the elevating plate 34 by the movement of the hydraulic jacks 32.

A modification of FIG. 4 is shown in the embodiment of FIGS. 5 and 6. That is to say, the square-columnar pressing block 69 is mounted swingably to the underside of the elevating plate '64 through hinges 89, when the block swings downward, it will extend further into the space C from the central part of the elevating plate; when it swings sideways, it will extend a shorter distance into space C. This is due to the con-figuration of block 69, namely, having a length greater than its width. Two hydraulic jacks 90 for turning said pressing block 69 are carried vertically and swingably with brackets 91 on both sides of said elevating plate 64; the end of each ram '92 of jack 90 is connected rotatably to the pin 93 which projects out horizontally from each side of said pressing block 69. The structural elements of the embodiment of FIGS. 5 and 6, mainly parts 62 to 66, 70 to 73, 76, 80, and 81, will be substantially indentical with the corresponding counterparts 32 to 36 of said second embodiment illustrated in FIG. 4. The scrap cars piled up in a plurality of stacks in the space C will be compressed with the downwardly extending pressing block 69 upon appropriate movement of the hydraulic jacks 62. Thereafter, said pressing block 69 is turned sideways to allow other uncrushed cars brought in and placed onto the already compressed scrap cars.

A fourth embodiment of a press for scrap cars will be described with reference to FIGS. 7 to 9. The hydraulic jacks 102, 202 for operating the press are located on the four corners of the oblong bed 101; further, the hydraulic jack 134 for tilting the elevating plate 104 is mounted on each side of a bed on bracket 135. Brackets 135 are mounted on bed 101 somewhat to the left of the center of bed 101 as shown in FIGS. 7, 8, and 9. The elevating plate 104 is mounted on brackets 137, 237, 138 respectively. The brackets 137, 138, are turnably mounted on the upper ends of rams 103, 136 of jacks 102, 134 respectively. The jacks 102, 134 are linked to each other through connecting bars 105 leaving an open space for the delivery gate 106 in the rear thereof. The brackets 237 near the delivery gate 106 are freely disconnectable from the respective rams by removing the headed knuckle pin 139; and the projecting end of said knuckle pin is freely removably inserted by a slip-proof plug 140.

The telescopic hydraulic cylinder 110 for feeding scrap cars is carried with brackets 111 on the central, fore part of the elevating plate 104; the end of its ram 112 is provided with a trolley 118 having a roller 117 on each side and also having a hook 116a on its underside. The rope means 113 put over said hook 116a comprises a wire rope 114 and two wire ropes 114a attached with hooks 115 connected with the lower end of said rope 114, and suspends downward through a lengthy slit 141 extending from said elevating plate 104 to the beam 120. For guiding the travel of said rollers 117, two rails 121 are laid one on each side of the slit 141. There is secured the pressure plate 144 on the underside of the elevating plate 104.

As means for discharging the compressed scrap cars out of the pressing space C, two wire ropes 142 are employed, whose one end is tied to the end of the bed 101 near the gate 106, while other end is fitted with a ring 143.

In the operation of the present device, said wire rope 142 is first made extended on the bed 101 longitudinally thereof. By extending the telescopic hydraulic jack 110 the rope means 113 is transferred up to the end of the beam from the condition of FIG. 7, whereupon the hooks 115 are put over the scrap car. Said scrap car is thence lifted up by elevating the elevating plate 104 by extending the hydraulic jacks 102, 202, 134. Thereafter, by telescoping said telescopic hydraulic jack 110 said scrap car is brought into the pressing space C, where the elevating plate 104 is lowered by telescoping the jacks 102, 202, 134, and said car is put down on the bed 101 on which the wire ropes 142 are lying. By repeating said operation a plurality of scrap cars can be piled one on top of the other. When the bringing of more scrap cars is impossible within the extent of the elevating strokes of the rams 103, 20-3, 136, the plug of the bracket 237 of each of the rear jacks 202 is drawn out and the knuckle pin 139 is also extracted, and in this condition the ram 136 is extended by operating the jack 134 alone, so that the elevating plate 104 lifting the used car to be brought in to the beam end is tilted as is shown in FIG. 9. By doing so, the beam end 120 will go up higher and therefore the scrap car will be lifted up further higher, so that more scrap cars can be easily piled up on top of each other in the pressing space. In this way, when sufficient scrap cars have been piled high enough to be subjected to the pressing action of the elevating plate 104, said elevating plate 104 is turned into its horizontal position followed by being lowered by telescoping each of the jacks 102, 202, 134, so as to compress said scrap car group with said pressing plate 144. Subsequent to the compression, said wire ropes 142 are put onto the hook 116a alternatively instead of said rope means 113 as is shown with chain from the pressing space C. In said discharging operation,

if a shift of said trolley is made after said elevating plate 104 is tilted, the discharge of scrap cars will be more accurately carried out. In addition, in said fourth embodiment of the inventive device, said intermediate cylinders 134 can be replaced with telescopic cylinders and thereby said elevating plate 104 can be inclined in higher positions, and therefore, the delivery and piling up of scrap cars can be more easily carried out.

Now, the fifth embodiment of the present scrap car press will be described in the following with reference to FIG. 10. The present embodiment illustrates a press of FIG. 4 installed on an automobile or a motor truck; the bed 151 is mounted on the frame 195 of a motor truck 194. The structural elements of this example 151 to 156, 159 to 178 will be substantially identical with the corresponding counterparts 31 to 36, 69 to 58 of the foregoing second embodiment. The hydraulic pump 198 for feeding pressure to each of said hydraulic cylinders, oil-tank 199,

motor 200, etc. will be preferably installed on the roof 197 of the drivers seat.

According to the above-said inventive device, scrap cars will be crushed in the pressing space C of the device, followed by being transported by the truck unalteredly as they are compressed in the same truck to specified melting regeneration plants.

Modifications of the embodiment as utilized with a common truck by installing therein the third inventive device of the foregoing FIGS. 5 and 6, and the fourth inventive device of the foregoing FIGS. 7 and 8, may be provided. In any modifications thereof, it will be easily understood that the construction of any cases conforms to the aforementioned fifth embodiment of the invention.

In the foregoing respective drawings, no conduit for feeding a fluid to each of the cylinders has been shown to make the illustration clear, but conduits herein used are conventional, common ones, and likewise used are common controlling means such as valves, and conventional means for preparing hydraulic fluid or other pressure fluid.

While particular embodiments of this invention have been illustrated and described, modifications thereof, as aforementioned, will readily occur to those skilled in the art.
